Gross primary productivity (GPP) is the rate at which - E: producers convert radiant energy into chemical energy
Gross primary productivity, or GPP, is the rate at which light energy or radiant energy is used to form and store chemical energy in sugar molecules during photosynthesis.
Producers use stored chemical energy for metabolism and cellular respiration for growth and development.
amount of living organic material is supported by a particular ecosystem.
the energy produced per unit area over a given time span
Thus, Gross primary productivity (GPP) is the rate at which - E: producers convert radiant energy into chemical energy
THE OCEANS ARE so vast and deep that until fairly recently, it was widely assumed that no matter how much trash and chemicals humans dumped into them, the effects would be negligible.
